We have a 2012 LT, purchased from Hertz in June with about 53k miles on it, now has about 62k. Long story short, we’ve had various warning lights, etc. go off, had a bit of fluctuation at idle, then lately started to stall when sometimes in idle, and finally the battery was dead when going to start it a couple mornings ago. As for the long version:
A couple months ago, the check engine light went on. Noticed some very slight RPM fluctuations at idle. Took it to AutoZone to have the code read, came up with something similar to my truck related to the MAF sensor…bought some cleaner, but didn’t really do much more checking into it. A couple days later, we had the coolant light go off. It stopped blowing hot air, and eventually started to overheat. We put some DexCool in, brought it to a shop who basically guessed that it had a bad thermostat. They also said that about eight codes came up. Ordered the part, and while waiting, started driving it a little and it never overheated again, so the part went back.
Started noticing that the fluctuations at idle were getting a little more pronounced…nothing as severe as what I’ve seen in some YouTube videos, but enough where we were just a tad concerned that it would stall after one of them. Then had the TPMS light go off…but after checking, nothing was wrong with the air pressure. Went along like this for a couple weeks, then other random notifications would come on, like the power steering and StabiliTrak lights. Then the radio would start cutting out and the headlights would flicker at the same time while driving on a few occasions.
Then about a week ago, went on a couple-hour cruise at night, with the fluctuations at idle getting a little wilder. Radio cut out a couple times on this drive. When we pulled up at home and put it in park, the car died. Happened again when parking after a normal half-hour or so drive. A couple days later, died at idle while waiting at a red light. And finally, it was completely dead when going to start it a couple days ago.
Do these symptoms sound the same or similar for anyone? Thanks!
